<p>Transforms enable you to convert existing Elasticsearch indices into summarized
indices, which provide opportunities for new insights and analytics.
For example, you can use transforms to pivot your data into entity-centric
indices that summarize the behavior of users or sessions or other entities in
your data.</p>
